1 Clemens 15

Let us cleave, therefore, to those who cultivate peace with godliness, and not to those who hypocritically profess to desire it. For [the Scripture] says in a certain place, This people honours me with their lips, but their heart is far from me. And again: They bless with their mouth, but curse with their heart. And again it says, They loved Him with their mouth, and lied to Him with their tongue; but their heart was not right with Him, neither were they faithful in His covenant. Let the deceitful lips become silent, [and let the Lord destroy all the lying lips, ] and the boastful tongue of those who have said, Let us magnify our tongue: our lips are our own; who is lord over us? For the oppression of the poor, and for the sighing of the needy, will I now arise, says the Lord: I will place him in safety; I will deal confidently with him.
